Can someone please explain what the major differences there are between Tuples and Dictionaries are and when to use which in Swift?
The tuples refer to the collections of various objects of Python separated by commas between them. The sets are an unordered collection of data types. These are mutable, iterable, and do not consist of any duplicate elements. In Python, the dictionary refers to a collection (unordered) of various data types.
Tuples have structure, lists have order. A dictionary is a key-value store. It is not ordered and it requires that the keys are hashable. It is fast for lookups by key.
It is well-known that in Python tuples are faster than lists, and dicts are faster than objects.
In Named tuple we assign individual names to each elements.
Define it like:
let nameAndAge = (name:"Midhun", age:7)
Access the values like:
nameAndAge.name nameAndAge.age
In unnamed tuple we don't specify the name for it's elements.
Define it like:
let nameAndAge = ("Midhun", 7)
Access the values like:
nameAndAge.0 nameAndAge.1
or
let (theName, thAge) = nameAndAge theName thAge
Tuples enable you to create and pass around groupings of values. You can use a tuple to return multiple values from a function as a single compound value.

A dictionary is a container that stores multiple values of the same type. Each value is associated with a unique key, which acts as an identifier for that value within the dictionary
